Background technology
Along with the quickening of Urbanization in China, carried out in a large number and reclaimed fields from the sea, fried mountain reclamation, adds that collapsible loess district of China and bury district are widely distributed, and therefore dynamic consolidation construction machinery will to maximization, seriation development.For the large dynamic compaction machinery ramming energy, in order to improve the hoisting speed of hammer ram, often adopting two lifting mechanism, above jib, just having two hoist ropes like this.Suddenly hammer ram is decontroled due to during strong rammer operation, hammer ram free fall, connect the steel rope of hammer ram in the moment decontroling hammer ram, because effect of inertia still can provide a upwards bounce suitable with hammer ram gravity, thus the bounce-back of generation fitfull is beated, the problem that two steel ropes easily kink in bounce-back hopping process, even also can jump to the opposite side of jib, together with being hooked on some part of jib, affect operating efficiency and safety.
As shown in Figure 1, on current dynamic compaction machinery, adopt above installs some segmental supports 2 ' at jib 1 ' more, and during use, steel rope 3 ' is through segmental support 2 ', limits the scope of beating of hoist rope 3 ' with this.
Jib is installed some segmental supports and can prevent hoist rope and some part hooking of jib, this situation for single raising line is very effective; But for the situation of two raising line, because two ropes are simultaneously through segmental support, so the situation that two ropes kink cannot be prevented.
Summary of the invention
The object of the invention is to propose a kind of can effectively prevent two raising line from beating in kink each other and with the anti-steel rope interference device of the dynamic compaction machinery of jib hooking phenomenon, dynamic compactor arm frame and dynamic compaction machinery.
For achieving the above object, the invention provides following technical scheme:
The anti-steel rope interference device of a kind of dynamic compaction machinery, comprises a limit rope support; Also comprise a T-shaped frame, three ends of described T-shaped frame are connected on described limit rope support, form two and can allow the active tunnel that two steel ropes separately pass through.
Further, three ends of described T-shaped frame are connected with described limit rope support by bolt.
Further, described limit rope support is the segmental support or U-shaped frame that are bent into by a bar.
Further, the vertical in opposite directions bending in two ends of described limit rope support, forms Yi shape.
The present invention also provides a kind of dynamic compactor arm frame, comprises jib body, and it also comprises the anti-steel rope interference device of dynamic compaction machinery in the various embodiments described above, and some described dynamic compaction machineries anti-steel rope interference device is disposed on the side of described jib body.
The present invention also provides a kind of dynamic compaction machinery, and it comprises the dynamic compactor arm frame in above-described embodiment.
Based on the arbitrary technical scheme in technique scheme, the embodiment of the present invention at least can produce following technique effect:
Because the present invention is provided with T-shaped frame, three ends of T-shaped frame are connected on limit rope support, define two and can allow the active tunnel that two steel ropes separately pass through, in strong rammer operation, two steel ropes are in fitfull bounce-back hopping process, limit rope support can stop two steel ropes and jib body generation hooking, two steel ropes then can be separated two active tunnels of formation by T-shaped frame, avoiding two steel ropes kinks together, efficiently solve the problem that in prior art, two raising line easily kinks, improve efficiency and the safety of strong rammer operation.
